Specification forming part of Letters Patent No. 184,654, d ated November 21, 1876; application tiled August 3, 1876.

To all whom it may concern:

Be it known that I, HENRY NIEMANN, of

Ypsilanti, in the county of Washtenaw and.

inatter more fully set i'orth.

In order to enable others skilled in the art to which my invention appertains to makeV and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whichliignre l is a perspective View ot' my beltfastening. Fig. 2 is a section ot' the fastening, showing the ends ot' the belt in position. Fig. 3 shows the parts ot' the fastening detached.

My belt-fastening is made in two pieces. Each of these pieces is composed of a plate having struck up from the center a series ot' concave-convex lugs, B, with openings between them, and along the outer edges of the plates A are formed teeth a. a, to go into the leather or other article used for belt.

The two parts of the belt-fastening are locked together by a bolt, G, passing through the interlocking staples B B, as shown, firmly holding the pieces together Withv the ends of the belt D between the teeth.

The fastening thus constructed may be made of steel or other hard material of suitable strength.

lt will be noticed that the teeth on opposite sides of the belt alternate, and there is an entirely smooth surface on the outside. The tension of the belt holds the bolt C in place.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

The within-descrbed beltfastening, composed ot' the plates A, each having the centra] concavo-convex struckup lugs B, and provided with the teeth a a, and adapted to be secured together by the locking bolt G, substantially as and for the purposes herein setforth.

ln testimony that I claim the foregoing as' my own l affix my signature in presence ot two Witnesses.
